DESCRIPTION & SPECIFICATIONS

Description:

Featuring 6 digits of bright, 7-segment LED displays, this unit is an integrating totalizer/ratemeter which accepts analog signal inputs. The unit can be field programmed to accept 0-20mA, 4-20mA, 0-5V, 010V or 1-5V signals. An optional Square Law input is available for inputs that require square root extraction. A 4-20mA output option is available to control strip recorders or other peripherals. Two assignable set points are standard for two stage shut off. The high and low scaling settings are programmable from the front panel. By pressing the "view" button, the unit will display: integrated total, rate, peak or valley. RS-422 or RS-232 serial communications are available options for data communication with a host computer.

Specifications: Display: 6 digit, .55" high, LED. Input Power: 110, 220 VAC ± 15% or 12 to 24VDC.

Current: maximum 300 mA DC or 10.0 VA at rated AC voltage. Output Power: (AC powered units only) + 24VDC. @ 50 mA regulated ±5%

Temperature:

Operating: +41°F (5°C) to +130°F (+54°C). Storage: -40°F (-40°C) to +200°F (93°C). Memory: EEPROM stores data for ten years if power is lost. Reset: Front Panel: resets displayed values and control outputs. Remote: 4-30 VDC positive edge, resets totalizer and control outputs. Control Outputs: Standard: Open collector sinks 250 mA from 30VDC when active. Optional: 2 each Form C SPDT 10Amp @ 120/240 VAC or 28 VDC. (Open collector outputs are also supplied with 10VDC provided at transistor outputs through relay coil. If greater than 2mA is used, relay will remain energized. Applying greater than 10 VDC may destroy unit. Transistor will sink 100mA in "ON" state.)

Input:

Standard: Linear 0-20mA, 4-20mA, 0-5V, 0-10V or 15V selectable from the front panel. Optional: Square Law 0-20mA, 4-20mA, 0-5V, 0-10V, or 1-5V, is available for inputs that require square root extraction.

Input Impedance: Current: 100Ω; Voltage: 115KΩ Calibration: The unit does all of the calibrations inter-

nally. There are no potentiometers to adjust and the unit never needs to be removed from the case.

Set Points: The two control set points can be set at any number from 0 to 59999. The set point outputs can be assigned to rate or total. The unit comes standard with two open collector control outputs. Two 5 Amp, Form C relays are optional. The outputs are programmable from .01 to 599.99 sec or latched until reset when assigned to the total and a hysteresis (alarm range) when assigned to the rate. Rate Display: Updates 5 times per second, Accurate to

4.5 digits. Set "low" greater than "high" for inverted display (LINEAR ONLY). Totalizer: Integrates from the rate reading and accumulates up to 6 digits of total count. The time base (hours, minutes or seconds) is field programmable from the front panel. Analog Out: The unit can be ordered with an optional 4-20mA output which is proportional to the rate display. The high and low settings are programmable from the front panel. Set "low" greater than "high" for inverted output. A sinking driver generates a corresponding linear current through the external devices. The output updates with each update of the rate. Accuracy is 50uA worst case. For rated accuracy, load must be connected to the analog output before unit is powered. Compliance voltage must be 3 to 30 VDC non inductive. (The unit can provide the DC source as long as the drop across the devices being driven does not exceed 21V). Programming: Decimal points, Scaling from 0 to 59999 units per selected time base, set points, input type, security lock code, and assigning outputs are all programmable from the front panel. Housing: Standard 1/8 DIN, high impact 94VO plastic case.

WIRING

AC / DC CONNECTIONS: NOTE: Connect power only after other connections are finished. Do not touch the live AC power terminals. The unit has been designed with an isolated AC input, therefore polarity is not a concern for the AC power. The chassis is plastic, therefore earth ground is not used. For DC operation, connect +DC to terminal 10 and -DC to terminal 3.

This Product complies with requirements of the European Community Directive 89/336/EEC [Electromagnetic Compatibility]. However, electrical noise or intense electromagnetic fields in the vicinity of the unit may disturb the microprocessor. Users should exercise care and should take proper precautions to avoid microprocessor disturbance.

Four common sources of noise are:

1) AC power line noise- The input power lines should not be common to power lines for motors, pumps, contactors, etc. If the unit cannot be connected to an electrically clean power source, an inductive load suppressing device (MOV as GE#V130LA1 or Resistor Capacitor as Paktron# .2uf/220 ohm @ 400V) can be installed. Although locating the suppressor across the AC supply at the unit should help, best results are obtained by connecting the suppressor across the leads of the "load" at the device causing the spikes.

2) Input line noise- The noise is carried on the input and DC ground lines. Make sure the input wires are not run into the unit in a bundle with power input lines. We recommend using shielded cable. Connect the shield to DC ground of the unit and "earth" at one point in the circuit preferably at the DC ground terminal of the unit.

3) Output lines- The unit has two open collector outputs and two optional relay outputs. When these outputs are used to run external relays or solenoids, spikes can be generated upon activation. This noise can spread through the instrument causing operating problems. If the source is a D.C. operated device, a general purpose diode (IN4004) placed across the solenoid prevents electrical noise spikes. Connect the cathode (banded side) to the more positive side of the coil. If the source is an A.C. operated device, use a Resistor Capacitor or MOV across the coil.

4) 24 VDC output supply- Noise can be generated on the 24 VDC output supply if it is used to drive inductive loads or if the current draw exceeds 50mA. Insure that all inductive loads have a diode (such as IN4004) across the coil and that the current does not exceed 50mA.

OPEN COLLECTOR & RELAY OPERATION

The open collector and relay outputs trigger when the total or rate (assignable; see programming step 2) equals the corresponding Preset (A or B). When the outputs are assigned to the "total", the operator can assign a duration of time (.01 to 599.99 sec.) that the output will remain energized. If 0.00 is assigned, the output will latch until reset. If output A is set at a duration (other than 0.00), the totalizer will autorecycle when Preset A is reached. At this time, output B will deenergize (if it was energized). Preset A is the final preset and should be set higher than Preset B, when both outputs are assigned to the total. If output A is set at a duration other than 0.00 and Preset A is set less

than Preset B, Preset B will be ignored (provided that they are both assigned to total). The totalizer will never autorecycle at Preset B. When the outputs are assigned to the "rate", the outputs can be assigned a hysteresis (alarm range). The hysteresis is the number of units below the preset that the output will remain energized. EXAMPLE: Preset set @ 100; Hysteresis set @ 10. The output will energize when the rate equals 100 and de-energize when the rate falls below 90 (10 below Preset).

NOTE: If the input scaling is inverted, the control output functions are inverted (LINEAR ONLY).

RS 232/422 OPERATIONS

This section applies to units which have the serial communications interface option. Up to 99 units can be linked together. Unit status can be accessed and many menu items can be entered through the serial port. Data is transmitted at selected baud rates using standard eight bit ASCII characters and one “stop” bit. The unit does not check or transmit a parity bit.

UNIT I.D. (DEVICE #)

Each unit in the hookup must be assigned a unit number from 1 to 99. This can be entered through the front panel (see step 5 of the programming section). If “00” is assigned, the unit can not be brought on line through the serial port. The units will remain in an “off” high impedance state until addressed by the assigned unit number. Once a unit is addressed, do not address another unit until the data has been sent and any data requested has been transmitted back.

BAUD RATE

The baud rate is the speed at which data is transmitted, expressed in bits per second. Baud rates of 300, 1200, 2400 or 9600 are available. Select the desired baud rate from the menu. (see step 5 of the programming section).

PRINT LIST

The serial interface card is equipped with a strobe line. When the strobe line is activated a user selectable set of data (print list) is transmitted. This transmission can be sent to a computer or printer. The print list consists of eight selectable items: COUNT, RATE, PEAK, VALLEY, PRE A, PRE B, LOW SET, HIGH SET. The list can be entered through the front panel (see step 5 of the programming section) or through the serial port (read on).

HELP

A help command has been installed for easy access of the command and data variables. When help is needed, type a “?” and press return (enter) whenever a unit is on line. The following list will be transmitted: D#XX: S Set E Exam R Reset G Lock L*List C*Count R*Rate P*Peak V*Valley A*PreA B*PreB L*Lo Set H*Hi Set J Lo Out K Hi Out N Norm D Unit E Input G Hy/DrA I Hy/DrB M Time T Baud W Lock X Meter Y A Typ Z B Typ O Code F RDec Q TDec U TFact The unit transmits the unit ID (D#XX) as well as the variables for the corresponding commands and data. A “*” indicates that the data is available for the print list.

When the unit is active (on line) it will operate in an echo back mode so that data sent from the terminal will be transmitted back for verification. When the unit is "on line", use the proper serial transmit commands to request data or set a new value. Be sure to send only one command at a time followed by a carriage return to insure proper operation. If an error is made, a correction can be made by back spacing and retyping correct data before the return (enter) is sent. Once a return (enter) is sent, the unit begins processing the data and will transmit the requested data on a nonpriority basis over the data transmit line. The unit will not transmit data if the Printer Busy line is activated (high). When the Printer Busy line is activated all transmissions are halted until the line goes low or open. There should be a pause after data is requested to insure that all data has been transmitted before making another request or addressing another unit. If transmission has not started within two seconds after data is requested, it can be assumed that there is a problem. The unit transmits a carriage return and line feed after each data value. The unit will stay "on line" until another unit is addressed.

SERIAL INTERFACE OPERATION:

Data is received and transmitted over standard EIA RS232 or RS422 levels. Each ten bit character is made up of a start bit, eight bit ASCII code and a stop bit. The input impedance of RS232 is 3KΩ to 7KΩ worst case. The terminal addressing the unit must be capable of driving all loads in the loop. The input impedance of RS422 is much higher and there should be no problem driving as many as 99 units. The transmit line remains in a high impedance "off" state until addressed. Only one unit is to be on line at a time!!! More than one unit on line could damage the unit or destroy the transmitted data.

RS232/RS422 - PC INTERFACE:

The following BASIC program is for setting up RS232/RS422 on serial port (#1) at 300 baud. Run this program after connecting the serial interface connections.
